To all whom t may concern.:

Be it known that I, BERG. HEINnloHs, a citizen of the United States.- and a resident of Anderson, in the county of Madison and State of Indiana, have invented certain new and useful Improvements in Machines for Making Corrugated Board, of which4 the following is a full,v clear, and exact description.

The invention relates to machines for mak ing 'corrugated or'other board and more particularly to the mechanism employed for ciittingthe continuous web into sheets of 'the desired size.

The object of theO invention is to provide improved cuttingv mechanism. Another ob-v ject is to improve the cutting mechanism set forth in an'application filed byA me August 18- 1919, Serial No. 318.088.P

2U The invention consists in the several novel features hereinafter set forth and Vmore particularly 'defined b-y claims at the conclusion hereof. v

In the drawings: Fig. 1 is a side-elevation.

Fig. 2 is anelevation viewed from the other side. Fig. 3 is a detail of the mechanism for rotating the cutter which is movably mounted on the reciproca-ting cutter-carriage. Fig. 4 is a section on line 4 -4 of Fig. 1. Fig. 5 is a longitudinal section. Fig. 6 is a view of the mechanism for ope-rating the rotatable cutter when it has been shiftedl to cut the web. Fig. 7 is a plan.

The machine comprises a frame 9 of any suitable construction. Rolls 10, which may be the final rolls acting on or feeding the web of corrugated board, are continuously driven by gears 11. one of which will be driven from the driving mechanism of the machine for -making the board and in'synchronism with the lfeed oftheweb to rolls 10. A gear-wheel 12. fixed tothe shaft of-the `lower roll 1.0. meshes with a pinion 13 on a shaft 14 which is mounted in bearings 15 on theframe 9. A sprocket wheel'16 on the shaft 14,'.a chain 17, driven by said sprocket` `fand a sprocket 18. fixed to a clutch-wheel 19, serve to drive said wheel continuously while the corrugated board machine is in op- 'pull the dogs into engagement conjointly 'shifted into or out eration. Wheel 19 constitutes the continu 50 ously driven member of a clutch, the operation of which is controlled by the web, for intermittently operating the cutter mechanism. Wheel 19 is loose on a. shaft 20 and serves to drive said shaft through a pair of dogs 21 which are connected by links 22 to a collar 23 fixed to said shaft. Springs 24, connected to said dogs respectively and to posts 25 on said collar, serve to normally with the internal friction-face 26 ofthe wheel 19. An' equalizing bar 2.7 is connected to the dogs by links 28. This bar causes the dogs to be of engagement with the clutch wheel 19'. A stop-pin 05 29 is fixed to one of the dogs and is adapted y to be caught by a notch 30 in a stop-lever 31 which has its lower end pivoted to the frame.` as at 32.- In operation, when the pin 29. passes into the notch 30 and is arrested by- 70 stop-lever 31, both of the dogs will. through -the equalizer bar'27, be held against rotation and disengaged from the clutch Wheel 19. Vhen the stop-bar 31 is withdrawn from the path of pin 2 9, springs 24 will draw 75 the dogs into operative engagement with :the frictionfface 26 of the clutch-wheel 19 and cause the shaft 20 to be driven. The stopnotch 30 and pin 29 'are adapted to arrest the shaft at but one point. so that upon each operation of the stop-lever the shaft 2O will make one complete revolution. A spring 31 tends to withdraw lever 31 lfrom the sto pin 29. A trip-lever 38 is pivoted to tle frame at 38a and is notched as at 38b to en- 85 gage a stud 31b on lever 31 and lock the lever 31 in position to arrest the stop-lever 29.

The clutch ris controlled to intermittently operate Vthe cutter mechanism by the web through electro-magnetic means adapted t0 90 operate trip 38 to release. the stop-lever 31. This 'means vcomprises a solenoid magnet 80 which has a helix4 81 supported in a jacket 82 which is sustained above the frame by a support 83, and an armature 84. A link 85 95 connects the lower end of said armature to the trip-lever 38, so the said lever will be lifted to lrelease lever 31 when 'the magnet gpg isenergiZed. rll`his maet is included'in an electric circuit comprising conductors 86, 87 and a switch comprising contacts 70 and 71.. '.llhis switch is mounted on a block 72 which is adjustably secured on a bar 73 by a clamp-screw 74. Contact -71 is secured to block 72 and contact 70 is carried by a lever 75 which is pivoted as at 76 to said l' block and has an extension 77 normally disclose the switch at contacts 70 and 71 W ich will close the` electric-circuit and energize magnet 80., The armature 84 `will then lift the trip-lever 38 to release the stop-lever 31 and spring 31a will then withdraw the stopf lever to release the clutch. The block7 2, on

i which the switch is mounted, is adjustable on the bar 73,- to and from the cutter-mechanism, so that the length of the sheets severed from the web may be varied as desired. rlPhis construction exemplifies intermittent mechanism for operating the cutters hereinafter described, which is electro-magnetitlly controlled by the end of thefweb and' is adjustable to sever sheets of different lengths from the web.

'llhe cutter-mechanism comprises a car-` riage44 which isslidablyymounted on the trame 9 and comprises a bed 45 over which the web is fed by rollers 10. A cutter 46 is .secured tothe front end of the bed 45 and a is mounted in lined bearings 54.

rotary cutter 47 issecured to a mutilated roller 48 which is mounted to rotate in bearings 49 on the carriage 44. Normally, when the cutter-'mechanism is at rest, the cutters .are in the relative position .shown in Fig. 3, so that the web will be free to pass between them untilthe rotary cutter is operated tn ward the cutter 46. yA sprocket 50 on the clutch-shaft 5"1 drives a chain 51 which operates a sprocket 52 on' a cross-shaft 53 which Crankdisks are secured to the ends otshaft 53 respectively. This driving connection for the shaft53 Aserves to operate this shaft a complete revolution every time that the clutch is rendered operative. Disks 55 serve to reciprocate the cutter-carriage 44 by means of links ,56 which are pivoted, as at 57, to the crank-disks, and,as at 58, to bars 59 .which are held von the sides ot'I the carriage 44 by bolts 60 which pass through slots 61 in said bars and permit movement of thc bars relatvely to the carriage. The bars 59 operate the carriage'through yielding connections consisting of rods 62 which are fixed to the bars 59 respectively and ass I and slide through guides 63' which are red Maaate web, so that when the latter is gripped be tween-the cutters, the yielding connections will permit the cutters to grip the corrugated board and keep it under a slight tension.

During the advance of the carriage with the web, the rotary cutter 47 will be operated to sever the sheet bytel lever 90 which is fixed to one end of the shaft of roll 48. A dog 95 on the roll 48 adapted to engage an adjustable stop-screw 96 which is carried by the inner end of a bar 97 fixed to the :cutterl carriage to normally position the rotary cutter sothe web can ass under it. A oneway dog 92 is pivo to the upper end of lever and has a tail 93 adapted to engage a stop-pin 94 on the lever. An abutment or cam 98E supported 'above the trame b a bar 99 engages the dog 92 during the orward movement of the carriage 40 and lever 90 to rock said lever and'cutter 47 to sever the sheet from the web as the carriage is moving forwardly with the web. A lug 109, which is adjustably fixed to the fra-me by bolts andA slots 101, engages the lower end of lever 90 to pivotally retract the lever as it reaches the limit of its forward stroke and after the dog 92 has passed under and cleared abut-- ment 98. A spring 91a is applied to dog 92 and connected to bar 97 to yieldingly hold the lever 90 and dog in normal position.

An abutment 102 fixed to the arriage 44 is adapted to engage the upper end ot'stoplever 31 as the carriage reaches the end of" its forward stroke, so it will be locked bythe trip-lever 38 and reeset in readiness for the succeeding operation.

That portion vof lthe web which projects beyond the cutter-roll is supported at. one

side by a rail l103 whilst its other side is uni supported. A rail 103 is supported lon legs 104 and an inclined support 105, consisting oflrails between legs 104 and base-boards 106, is dis osed to catch the sheets after they have een severed from the web, the

sheets falling by gravity onto said supportand forming a stack.

A cam 120 is tired on the clutch-shaft 20 to operate a lever 121 which is pivoted to the frame, as at'122, and is connectedv by means of a rod 123 and lever 124, to operate a lll() llllti K brake-band 125 adapted to engage one'of the crank-disks 55. Lever 124 is p lvoted to the frame, as at 126, and both'ends of the brakeboard ,are connected to* said' lever. This cam is shaped to apply the brake-band to check the movement of the cutter-mechanism before it is arrested by the stop-pin 29 and lever 31 and to'hold said mechanism While the clutch is inoperative. This brake and its operating mechanism exemplifyy automatic means for checking .the cuttermechanism in starting and stopping.

In operation, the finished corrugated web will be fed continuously from the rolls 10 and every time its front edge strikes and shifts the Switch-lever 75, the ycircuit for the magnet 80 will beclosed and the helix of `said magnet will be energized. That will voperate armature 84to lift the trip-lever 38 jolution of shaft 53 and the clutch, will reciprocate the cutter-'carriage 45 and the cutters thereon. During the forward stroke of the carriage, dog 92 on lever 90 will strike a stationary cam 98 and this will rock said lever and the rotary cutter 47, to sever the Web. While the carriage is still moving 4forwardly, the dog 92 will pass under and clear cam 98. During the end portion of the forward stroke of the carriage, thelower end of lever 90 will encounter t-he stationary stop 100 to positively retract said lever and rotary cutter so the .web may again pass between the cutters. During the retraction of the carriage, dog 92 will ride under cam 98, and the lever 90 will be held in its normal position by spring 91". Near the end of the retractile stroke of the carriage, dog 102 on the carriage -will strike the upper end vof stop-lever 31 and shift it into position to be locked by the trip-lever 38 in position to stop the clutch at .the end of each revolution v.

thereof. lAfter the web operates the switchlever75, its extension 77 will pass under the web to permit it to continue its forward movement until the sheet has been severed. The magnet will beA cle-energized by the breaking of the circuit at contact 7 0, 71 during the retraction of the carriage and as ysoon as the switch-lever is releasedV by sheets.

The brake-band 125 is automatically applied by cam 120 'before the clutch-stop, to

. check the cutter-mechanism and prevent objectionable shock or displacement 'of the parts.

The invention exemplifies improved means for automatically operating the rotatable cutter on the reciprocable carriage and checking-meansl for y the cutter-mechanism.

The invention is not to be understood as l restricted to the details set forth, since'these may be modified within the scope ofthe ap- .v

pended claims,l without departing yfrom the spirit and scopel of the invention.
